Anker SOLIX C1000: Runtime & Specs
By Hicham M. · Specs from Anker SOLIX's published documents, as of September 2026 · How we calculate
The Anker SOLIX C1000 is a 1,056 Wh LiFePO4 power station with 1,800 W of continuous AC output and a 2,400 W surge rating. It runs a typical full-size fridge for about 15 hours.

Simulated runtimes (not measured)
Nobody tested this unit for this page. These figures come from a computer simulation of the C1000, and they are estimates. The plain runtime table below divides energy by average draw at 85% efficiency. The simulation also charges the battery for the power the inverter burns just by being switched on, which is why small loads come out shorter. Where we have measured a unit, the measurement is shown separately and labeled as measured.
| Device | Spec-sheet math | Simulated, typical | Likely range | Simulated at 0 °C |
|---|---|---|---|---|
| Wi-Fi router + modem | 2.5 days | 27 hours | 24 hours to 34 hours | 23 hours |
| CPAP (no humidifier) | 30 hours | 19 hours | 17 hours to 22 hours | 16 hours |
| Starlink Standard | 10 hours | 8.8 hours | 8.2 hours to 9.3 hours | 7.5 hours |
| Refrigerator (full-size, ENERGY STAR) | 15 hours | 13 hours | 11 hours to 14 hours | 11 hours |
Nonstop runtime from full to battery cutoff. Likely range = middle 80% of 200 simulated runs with the uncertain inputs varied. The inverter idle draw is assumed, not published: we assumed about 19 W for this model, varied from 11 to 28 W. If the real figure is lower, real runtimes land closer to the spec-sheet column.
How this was simulated
- The battery is stepped down every 2 minutes until it reaches cutoff, for 200 runs per device. Results are seeded, so the page shows the same numbers on every build.
- Battery draw = load + inverter idle draw + 4–8% of the load + a loss that rises with load squared (4% at full output).
- Usable capacity = 92–98% of rated Wh, for protection cutoff and aging.
- At 0 °C, 80–90% of that capacity is assumed available.
- Fridges cycle on and off every 30–50 minutes at the share of the time set by their average draw. The inverter idle draw continues while the compressor is off.
- Devices that exceed this model's output or surge rating are left out. Loads are US 120 V devices.

Solar charging time
Hours of good sun to charge from empty, assuming panels deliver 75% of their rating.

| 100 W of panels | 75 W | 14 hours |
| 200 W of panels | 150 W | 7 hours |
| 400 W of panels | 300 W | 3.5 hours |
| 600 W of panels | 450 W | 2.3 hours |
